Design and Development of Cost Effective Switch Mode Power Supply

Abstract

Efficient conversion of electrical power is becoming a primary concern to companies and to society as a whole. Switching power supplies offer not only higher efficiencies but also offer greater flexibility to the designer. Recent advances in semi-conductor, magnetic and passive technologies make the switching power supply an ever more popular choice in the power conversion today. In the industries nowadays three phase supply is a prime need for their utility. Power controllers, AC Drives, DC Drives are the major devices used for different purposes. As SMPS have very efficient performance, not to keep it limited to lower voltage input range, but can be introduce it for the higher voltage inputs and enhance its versatility.As Switch Mode Power Supply has different Topologies like Flyback, Pushpull,Half bridge, Full bridge and Forward. In this Project, by using Forward Topology and PIC controller as control scheme, size and cost of Switch Mode Power Supply can be decreased as compared to the other Topologies. The objective of this project is to fabricate the compact size and cost effective Switch Mode Power Supply by using Forward Topology. The results of Hardware are shown for all different available solutions. SMPS by using forward topology gives reliable and cost effective solution with compact design.
